What is Double?

Double is turning its accounting assistant into the way the work gets done

Double ships weekly, and nearly every release extends Ask Double rather than the surrounding application. In the last two months it has learned to build workpapers by reconciling accounts against supporting documents, import accruals, create and manage client metrics through the MCP and API, take voice input, and — in private beta — reach into Slack, Notion, and HubSpot. The non-assistant work fills in what firms need to trust that: role-based restrictions on editing client properties, and check transactions in AI Transactions.

What is Prowlarr?

A steady indexer-maintenance cadence: fixes, definitions, translations, repeat.

Prowlarr ships every week or two off the develop branch, and the entries are consistently small: indexer definition corrections, parsing fixes, dependency bumps and Weblate translation batches. The only user-facing addition in this window is showing indexer-specific categories in search. Every entry opens with the same boilerplate about switching update branches, which is the feed's own shape rather than news.

Double is turning its accounting assistant into the way the work gets done

◆ Current state

Double ships weekly, and nearly every release extends Ask Double rather than the surrounding application. In the last two months it has learned to build workpapers by reconciling accounts against supporting documents, import accruals, create and manage client metrics through the MCP and API, take voice input, and — in private beta — reach into Slack, Notion, and HubSpot. The non-assistant work fills in what firms need to trust that: role-based restrictions on editing client properties, and check transactions in AI Transactions.

◆ Where it's heading

The assistant is moving from answering questions to performing the billable work — tie-out, accrual setup, metric standardization across a whole book of clients. Each release pairs that with an access or permissions control, which is the pattern of a vendor that knows the objection is liability rather than capability. The accounting engine itself keeps advancing underneath, most recently with prepaid contracts paid in installments.

◆ Prediction

Given the review-and-signoff question these features raise, the likely next step is an approval or audit trail around what Ask Double produces rather than another task it can perform.

5.0

A steady indexer-maintenance cadence: fixes, definitions, translations, repeat.

◆ Current state

Prowlarr ships every week or two off the develop branch, and the entries are consistently small: indexer definition corrections, parsing fixes, dependency bumps and Weblate translation batches. The only user-facing addition in this window is showing indexer-specific categories in search. Every entry opens with the same boilerplate about switching update branches, which is the feed's own shape rather than news.

◆ Where it's heading

The value being shipped is upkeep of the indexer catalogue — PreToMe categories, M-Team category updates, MyAnonamouse author name handling, IPTorrents query parameters. That is the actual product for an indexer manager, but it means the release history reads flat: no architectural change, no new integration surface, no shift in what Prowlarr does. Version numbers move faster than capability.

◆ Prediction

Expect the same rhythm — per-indexer definition fixes and dependency bumps cut every one to two weeks — with any notable change arriving as a small search or UI addition rather than a release theme.
